Processes Eating Up Cpu
Feb 12, 2008
Got some processes that regularly eat up my cpu resources:
%CPU 36.0netstat -plan
%CPU 36.0 /usr/local/apache/bin/httpd -k start -DSSL
%CPU 6.2httpd [truncurl.com] [/leisha?.jpg]
Note leisha.jpg does not even exist!!
%CPU 7.0 /usr/local/bin/python2.4 -S /usr/local/cpanel/3rdparty/mailman/cron/disabled
Something is going seriously wrong with my server,
what can I do ?
My server is frequently down because of kmemsize errors and I'm sure something is misconfigured.
Will try to disable mailman now, pretty strange to find that in my log.

Apache is wasting away a bit over a GB of memory at about 100 connections. Is this something normal? Or should I be receiving a little better performance? Also, I find that the load is very low. Is there anyway to sort of trade a bit of the CPU Usage for some more memory?

We have a Dedicated Hosting Account running with the following configuration: QTY Hardware Component 1 Supermicro Dual Xeon SATA X5DPA-TGM 2 Intel 2.4 GHz 533FSB P4 Xeon 4 Generic 512 MB DDR 266 ECC Reg 2 Western Digital 160GB:IDE:7200rpm 160GB 1 Unknown Onboard IDE Installed Software - Urchin Urchin 5 - Redhat Enterprise Linux - OS ES 4.0 - cPanel, Inc. cPanel STABLE We are using Exim for the mail server. The Server Load reaches upto 35-40.00 every now and then and apparently Exim eats up most of the Resources. I am attaching a few Screens with the output of Command line top and the WHM Process Manager. You can see there are a lot of exim Processes/threads running. how to Optimize the Server for this.

I'm running 4 websites on a quad core xeon x3220, with 2gig of ram. It's 4 proxy sites, they are running fine and dandy, except for the fact that even when their is little traffic going to them ram is still just as high. I'm running debian 4.0, and heres a copy of my footer Apache/2.2.3 (Debian) mod_python/3.2.10 Python/2.4.4 PHP/5.2.0-8+etch11 mod_perl/2.0.2 Perl/v5.8.8. I'v modified nothing since I got the server, I installed apache2, and awstats, that's it. I'v read up about optimizing and it hasn't helped much, and I thought maybe their is proxy specific tweaks I could make to the conf.

My RAM is 2G. The cache memory of my server is eating, After 2 weeks, the cache memory is below 1G, then the server crashed. After I reboot the machine, the cache memory back to normal. But it starts to eating again. I have attached the graph. I am using lighttpd, php, mysql

I just recently switched to using fcgid with cPanel and was wondering how I can go about seeing what is actually running under each process. Before when I was running PHP as CGI I could do psauxwe|grep PID and see all the environmental variables along with the path. I'm not able to do that any longer with fcgid. Is there anyway to get this info now?

Well one of my servers has been under a DDoS attack for a while and I've been doing things to keep it down but there is a suspicious process that keeps running and I am guessing that is whats keeping the server load up because when I stop apache the load goes down but not for long. The process is this: Code: /opt/adobe/fms/fmscore -adaptor _defaultRoot_ -vhost _defaultVHost_ -app registry -inst registry -tag -conf /opt/adobe/fms/conf/Server.xml -name _defaultRoot_:_defaultVHost_:registry:registry: Does anyone know what this process is or how to block it?

On jaguarpc.com, their terms of service state, "We do not allow programs to run continually in the background. This is to minimize system resources used and operational maintenance needed. We do not allow any chat or topsite programs on our servers other than the ones we pre-install for our clients to use. IRC: We currently DO NOT allow IRC or IRC bots to be operated on our network." I thought the whole point of using a VPS was so you could run a continuous application (like a chat/game/etc server)? Why are so many VPS services against IRC (the chat server I use is not IRC based, but I just think its wierd so many prohibit IRC)

I'm having a problem with one user account, every 5-10 minutes a spamd process of this user gets locked using 60-90% cpu and never ends. If I don't kill the process another one does the same and they all get locked causing very high loads I reinstalled exim but it did nothing The problem persisted even when this user's account was suspended

OS: CentOS 5 Software: Apache 2 / PHP CGI 5.8 / suPHP Today I took the leap and switched to suPHP, rather than the Apache module. This is just what suited us best for hosting our own websites, keeping them more isolated from eachother bar a certain shared directory. All is great, apart from I'm now noticing Zombie processes all of the time. These processes do seem to go away though, if I watch top the amount of Zombie processes will go up and down between 0 and 10. Code: 17471 gnation 15 0 0 0 0 Z 1 0.0 0:00.03 php-cgi <defunct> 17463 gnation 16 0 0 0 0 Z 1 0.0 0:00.02 php-cgi <defunct> 17467 gnation 16 0 0 0 0 Z 1 0.0 0:00.02 php-cgi <defunct> Are these processes a problem, considering they do leave after a while? I've read up about Zombie processes and it would seem that as long as they are closing at some point, instead of hanging around, then that's fine. Is this supposed to happen in my setup?

I recently modified my loadavg script to store in a database the output of a top command if there's ever server loads of over 1. Overnight I've had 12 such times logged to a database. Upon inspecting things (I was expected there is a recurring problem), the top command reveals that there are always three queries running together which take over 30 seconds each, and take up ~9% of memory each: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26119 nobody 25 0 73492 38m 4792 S 0 8.5 0:30.00 httpd 7313 nobody 25 0 76716 42m 4992 S 0 9.5 0:29.99 httpd 14212 nobody 19 0 70688 39m 4844 S 0 8.8 0:30.03 httpd Is there a command that will tell me exactly what these processes are? Like in WHM's "CPU/Memory/MySQL Usage" whereby it says what account these httpd processes are coming from, and the actual page they are coming from as well? If I could log these details (i.e. account and page these are coming from) along with the output of the top command, I can hopefully troubleshoot where this problem is coming from.

i am facing slight problem with one of my VPSes. It had happened earlier also but had got resolved automatically. Please see this screenshot: [url] i know that the server load is not that great to cause this much SWAP usage. i think this is because of the processes not getting killed. UPDATE: here is the screenshot of my other server with the same provider. which is not really overloaded but i think is facing the same problem of processes not getting killed [url]

so here is a simple question that i just can't seem to figure out.. when i run the command top or ps -auxw.. they show the httpd processes as the command httpd or /usr/sbin/httpd, but how do i know what file that is? is there anyway to find out what file that is actually getting executed or served?

Is there a way to prevent a certain service from taking up a certain amount of load on the server? Like, shouldn't there be a way I can tell gzip or exim how much server load they are allowed to take up on my server? I know it may run them slower, but it will be for the better if I could set each one to only be able to have a max load peak or something.

When I run the command - uptime; free -m; mysqladmin processlist - I get a list of my mysql activity. There are about 10 sleeping processes for mysql on one of my accounts. Does anyone know why mysql processes might be sleeping like this? For the record, there is a very quiet PHPBB forum running on the site in question.

I have some problems with apache. As you can see below, long-live httpd processes use a lot of CPU / Ram. Usually this processes caused high LA - 8-12. Code: %CPU CPU NI S TIME COMMAND 0.2 - 0 S 00:00:27 nginx: worker process 0.3 - 0 S 00:00:29 nginx: worker process 0.3 - 0 S 00:00:30 nginx: worker process 3.3 - 0 S 00:04:09 /usr/local/apache/bin/httpd -k start -DSSL 3.4 - 0 S 00:04:16 /usr/local/apache/bin/httpd -k start -DSSL 3.5 - 0 S 00:05:50 /usr/local/apache/bin/httpd -k start -DSSL 3.6 - 0 S 00:05:40 /usr/local/apache/bin/httpd -k start -DSSL 3.6 - 0 S 00:05:16 /usr/local/apache/bin/httpd -k start -DSSL 3.6 - 0 S 00:06:04 /usr/local/apache/bin/httpd -k start -DSSL 3.7 - 0 S 00:06:06 /usr/local/apache/bin/httpd -k start -DSSL 3.7 - 0 S 00:00:55 /usr/local/apache/bin/httpd -k start -DSSL 3.7 - 0 S 00:06:10 /usr/local/apache/bin/httpd -k start -DSSL 3.7 - 0 S 00:06:10 /usr/local/apache/bin/httpd -k start -DSSL 3.7 - 0 S 00:06:10 /usr/local/apache/bin/httpd -k start -DSSL 3.8 - 0 S 00:06:12 /usr/local/apache/bin/httpd -k start -DSSL 3.8 - 0 S 00:05:40 /usr/local/apache/bin/httpd -k start -DSSL 3.9 - 0 S 00:06:28 /usr/local/apache/bin/httpd -k start -DSSL
